I'm working on some ground cover, and was wondering if anyone could help with an extremely visible section of the average layout. In the picture below, I have started with a sifted dirt / sand mix, with a little WS turf, small rocks and clumped foam. This is still wet here. This will be the first of a few "layers", hopefully creating a reasonable facsimile of what one might actually see on the ground. What do you do for ground cover? How do you do it? Hints? Tips? Thanks!
